Answer:
|CE|=2
Step-by-step explanation:
The quadrilateral is shown in the attachment
Recall that the diagonals of a rectangle are congruent.
This implies that:
|AC|=|BD|
We substitute the expressions to get:
This is now a linear equation in one variable.
Group similar terms to get:
Simplify to get:
15=3x
Divide both sides by 3 to get:
Recall again that the diagonals of a quadrilateral bisect each other.
Plug x=5
